The problem of “frequent fliers” is not a new one for the city’s emergency responders. A small group of serial 911 callers have long consumed a disproportionate share of D.C. Fire and EMS time and resources. But, the Post’s Amy Brittain reports, the city is taking court action against one of the most frequent of frequent fliers, seeking to have a guardian appointed for Martha Rigsby, 58, who in the past year alone has “accounted for 226 calls to 911 and been whisked by an ambulance to a hospital 117 times.” The Trinidad resident has racked up a $61,000 bill for ambulance rides but has also put herself in danger, a city psychiatrist testified, “from falls under the claim of ‘seizures’ or ‘Narcolepsy,’ which have never been correlated with medical findings.” Rigsby is fighting the guardianship petition in court and addressed her frequent calls for help after a recent hearing: “Well, I don’t do it on purpose,” she said.
